I guess the issue with Jon Johanson is the balance between:
1. Pushing the boundaries, breaking the rules, going further to achieve very difficult goals.
2. Putting others to considerable extra work, cost (and personal risk if they would have had to send a search party for him somewhere).
I had a friend rescued from his dinghy after trying to row the Pacific. The Australian Navy rerouted a Destroyer to go and get him and his colleague. Cost estimated at $300K+ - the Australians were not happy. Does that mean that nobody should try to row the Pacific? Perhaps, perhaps not.
Crucially, though, in both these examples they were actually doing what they said they were going to do....
